Problems solved by technology

However, the application of FMLOC on large-scale electronic products often requires longer metal traces (touch signal lines) to connect the touch electrodes inside the touch area and the peripheral driver chip (IC), and the longer metal traces are easy to A large amount of static electricity is accumulated and released, which leads to the occurrence of Electro-Static discharge (ESD), thereby reducing the yield of products. Therefore, FMLOC needs to be applied to large-scale electronic products to solve the problems caused by excessively long metal traces. ESD problems

Abstract

The invention discloses a touch substrate and a touch display device, which are characterized in that at least one touch signal line is designed into at least two first lines with short line structures, and the two first lines are connected through a connecting line in a manner of forming holes in an insulating layer, so that a complete touch signal line is formed; the design of the touch signal line can effectively reduce the static accumulation capacity caused by the long routing design of the touch signal line in the manufacturing process, so that ESD is prevented, and the yield of products is improved.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch substrate and a touch display device. Background technique [0002] With the development of active-matrix organic light emitting diode (AMOLED) technology, the development of display devices has entered the era of full screen and narrow frame. In order to bring users a better experience, full screen, narrow Frame, high resolution, curly wearable, folding, etc. will surely become important development directions of AMOLED in the future; in order to make the Panel lighter and thinner to adapt to future folding and curly products, the flexible multi-layer structure (Flexible Multi-Layer On Cell, FMLOC ) Touch technology was born. With the development of the market, AMOLED technology has gradually been applied to electronic products of small size to large-size electronic products. The application of FMLOC in large-size electronic products is bound to be a futu...
